Description and Introduction

Up to 2 A step down switching regulator The L5985TR is a step-down switching regulator manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Type:** Step-down switching regulator  
- **Output Voltage:** Adjustable from 0.6V to VIN  
- **Input Voltage Range:** 2.9V to 18V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 250kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 93%  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** HSOP-8 (Exposed Pad)  

### **Descriptions:**  
- The L5985TR is a monolithic step-down switching regulator with internal power MOSFETs.  
- It is designed for low-voltage applications requiring high efficiency and compact design.  
- The device supports adjustable output voltage and switching frequency.  
- It includes protection features such as thermal shutdown, overcurrent protection, and undervoltage lockout.  

### **Features:**  
- **Internal Power MOSFETs:** Reduces external component count.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Synchronous Rectification:** Improves efficiency.  
- **Soft-Start:** Prevents inrush current at startup.  
- **Pulse Skipping Mode (PSM):** Enhances efficiency at light loads.  
- **Thermal Shutdown:** Protects against overheating.  
- **Overcurrent Protection:** Safeguards the regulator and load.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This information is based solely on the manufacturer's datasheet and technical documentation.
